Datasheet PDF of 204 KB for the 2N3771, a JEDEC 2N-series transistor, catalogued in the schematic section.

Part number 1SS345 is the only information in this 58.3 KB PDF name, so no laptop, board or revision is identified.

Part number 1SS196 gives this 68.1 KB PDF its name, which marks it as a datasheet for a single semiconductor rather than a full circuit diagram.

Filed among schematics, this 61.3 KB PDF actually documents a single part, the JEDEC-registered 1N485B diode.

Component datasheet for the 1N457, a JEDEC 1N-series diode, saved as a 62.5 KB PDF and categorised here as a schematic.

Datasheet for the 1N5059 diode as a 52.4 KB PDF, filed in the schematic category though it is a part specification sheet.

Two part numbers appear in the name, 1N914 and 1N916, so this 78.8 KB PDF is a shared datasheet for two related JEDEC 1N diodes rather than a board schematic.

Covering the range 1N821 to 1N829, this 41.9 KB PDF is a series datasheet for a family of JEDEC 1N diodes, despite being indexed as a schematic.

A small PDF of 48.8 KB indexed under schematics, whose name points to a 44-lead PLCC package, most likely a package outline or socket drawing rather than a full circuit…

The file 30WQ03F is a 38.7 KB PDF that, despite its schematic label, appears to be a datasheet for a single rectifier diode, judging from the naming.

Notebook mainboard schematic for Quanta project UW1, about 1022 KB as a PDF. NB in the name most likely just means notebook, and no revision, brand or chipset is given…

Merged PDF of application circuits for the STK41XX series, the Sanyo thick-film hybrid power amplifier modules used in many audio systems and mini components.

Small 21.8 KB PDF titled as a dock test diagram, with no device model, brand or board number stated in the name.

Laptop mainboard schematic for the Quanta Y19C project, revision 2A, in a 3.30 MB PDF. The file name carries no brand, model or chipset details, only the ODM code and…

Schematic for the HP Compaq Presario 2200 series notebook, a 970 KB PDF. No motherboard number, ODM or revision appears in the file name, so check the title block…

Schematic for the HP HDX9000 series notebook, built by Inventec under the project name Orion.

Lenovo laptop schematic for the NM-A281 mainboard, an LCFC design, supplied as an 878 KB PDF whose name carries no revision.

Part document for the 2SC4517, a 27.9 KB PDF listed as a schematic; the name holds only the part number.

Datasheet-style PDF covering the BD233, BD235 and BD237 family of medium-power transistors, filed here under schematics.

The 3N258 is the subject of this 42.2 KB PDF, indexed as a schematic but in practice a component reference.

Named 3LN02C, this 41.8 KB PDF is filed among schematics but its name is a component-type code with a C suffix and gives no device or board details.

Another copy of documentation for the 2SD1458 NPN transistor, stored as a 48.8 KB PDF under a lowercase file name.

A fairly detailed 200 KB PDF for the 2SD2352, a JIS-numbered NPN transistor, where the 2SD prefix denotes NPN low-frequency parts.

The 2SK2750 is covered by this 394 KB PDF, indexed as a schematic but most likely the component datasheet, since 2SK is the JIS prefix for N-channel FETs.

A 135 KB PDF covering the 2SK2711 transistor. The extra 1-5 token in the name is not explained and may point to a page range or document revision.

The smallest sheet of its group at 24.4 KB, this PDF concerns the 2sk2573, an N-channel field-effect transistor by the JIS 2SK prefix.

Reference PDF for the 2SK2459N, sized 133 KB and indexed as a schematic, though the JIS-style name points to a single-component datasheet for an N-channel FET.

Datasheet-style PDF for the 2SK1412LS, a Japanese 2SK-series N-channel field-effect transistor, filed in the index under schematics.

Reference PDF for the 2SK620, a JIS-series N-channel field-effect transistor, weighing 35.6 KB and listed under schematics though it is most likely a datasheet.

Only the part number 2SJ512 appears in the name of this 455 KB PDF, which the index lists among schematics.

The 2SJ419 is covered by this 100 KB PDF, filed under schematics though the part number points to a discrete transistor datasheet.

Indexed as a schematic, the 44.5 KB PDF named 2SD1328_E should be a datasheet for the 2SD1328, which the JIS 2SD prefix identifies as an NPN bipolar transistor for…

Small 31.3 KB PDF covering the 2SC5265LS, filed as a schematic. The 2SC prefix in the JIS system identifies an NPN bipolar transistor, and the LS suffix marks a variant…

Named in lowercase for the 2sc4132, this 63.0 KB PDF is classed as a schematic but is better understood as the datasheet for an NPN bipolar transistor, which is what the…

Small 95.8 KB PDF for the 2SC4109, indexed with the schematics. The file name gives nothing beyond the part number; the 2SC prefix identifies an NPN bipolar transistor…

Small 30.5 KB PDF for the 2SC5808 part, an NPN bipolar transistor per the Japanese 2SC designation.

Datasheet-sized PDF of 38.0 KB for the 2SC5474, with an _E suffix in the name that likely marks an English edition; that reading is an inference.

Small PDF of 25.0 KB dedicated to the 2SC4064, catalogued as a schematic. Going by JIS semiconductor numbering, 2SC marks an NPN bipolar transistor; the name gives no…

For the 2SC4006 there is this 79.6 KB PDF, filed as a schematic though a bare JIS code like this normally names a datasheet.
